4430 Planer
Step 2: Setting Depth of Cut and Feed Rate
This planer is capable of removing at most 1/8” per pass. For stock that is less than 8” wide, the planer
can cut as much as 1/4" per pass. For best results, it is recommended to take light passes with low feed
rate when approaching the desired thickness.
Wood Hardness
Depends on the hardness and brittleness of the wood type, operator should adjust the maximum depth
of cut and feed rate accordingly. For workpiece that is hard/brittle, reduce the depth of cut and feed rate.
For your reference, this Janka scale shows the hardness of wood types that are commonly used. It ranks
the hardness of various wood types by measuring the amount of force (in lbs.) required to embed a 0.444”
steel ball halfway into the wood.
